What are transactional emails?
Transactional emails are automated messages triggered by user actions or system events, such as password resets, order confirmations, or alerts. They differ from marketing emails and are sent via the ClickSend API or SMTP.
ClickSend only offers transactional emails. If you want to send email marketing, it’s best to use another provider.
How to send transactional email
Transactional emails are always sent via the ClickSend REST API or SMTP server.
View the API email docs to set up transactional email.
Adjusting your email settings
While you will send email via our REST API, you’ll still need to set up delivery reports and your ‘from’ address in the Dashboard. Here's how:
How to set up delivery reports
Navigate to the account dropdown in the Dashboard
Select Message Settings > Email
Select Delivery Report Rules and then Add New Rule
Give the rule a name
Provide the URL that you want the delivery report sent to
Click Add
How to set up your from address
If you don’t set up your from address, it will be the address associated with your ClickSend account by default.
Navigate to the account dropdown and select Message Settings > Email
Select From Addresses and then Add New Email Address
Enter the email address
Click Add
SMTP server for outgoing transactional email
Server: smtp.clicksend.com
Port: 25 (Non-encrypted) or 465 (Secure SSL).
If you're having issues, try 587 or 10001 (Non-encrypted).
You will also need to provide your account credentials with the following:
Username: Subaccount username
Password: API Key
Before you start sending, you'll need to verify your 'From' email address in the Dashboard.
